FlashPix Tags

The FlashPix file format, introduced in 1996, was developed by Kodak,
Hewlett-Packard and Microsoft. Internally the FPX file structure mimics
that of an old DOS disk with fixed-sized "sectors" (usually 512 bytes) and a
"file allocation table" (FAT). No wonder this image format never became
popular. However, some of the structures used in FlashPix streams are part
of the EXIF specification, and are still being used in the APP2 FPXR segment
of JPEG images by some digital cameras from manufacturers such as FujiFilm,
Hewlett-Packard, Kodak and Sanyo.

ExifTool extracts FlashPix information from both FPX images and the APP2
FPXR segment of JPEG images. As well, FlashPix information is extracted
from DOC, PPT, XLS (Microsoft Word, PowerPoint and Excel) documents, VSD
(Microsoft Visio) drawings, and FLA (Macromedia/Adobe Flash project) files
since these are based on the same file format as FlashPix (the Windows
Compound Binary File format). See
http://graphcomp.com/info/specs/livepicture/fpx.pdf for the FlashPix
specification.

The DocumentSummaryInformation property set includes a UserDefined property
set for which only the Hyperlinks and HyperlinkBase tags are pre-defined.
However, ExifTool will also extract any other information found in the
UserDefined properties.
